Re: [go-nuts] http.shutdownPollInterval documentation

[Sridhar]

Thanks. I was fairly certain that's what it meant. 

Wasting more time, the pedant in me argues - but 

"Left as an exercise for the reader" generally implies it's a solved 
problem and the reader is to take time to re-solve to hone their skills.

It's not from a book.  "Left as an exercise for the reader" is just a
saying.  It means, approximately, "we're not sure how to do it, but if
you can figure it out, please send a fix."

[go-nuts] http.shutdownPollInterval documentation

[Sridhar]

In https://golang.org/src/net/http/server.go the documentation for 
shutdownPollInterval (admittedly unexported) reads:

// Ideally we could find a solution that doesn't involve polling,

// but which also doesn't have a high runtime cost (and doesn't

// involve any contentious mutexes), but that is left as an

// exercise for the reader.

Is this a remnant from a book on Go ? If so which one ?
